oLovER-HULLEFL SPECIFICATION forming part of Letters Patent No. 316,210,dated April 21, 1885.

Application filed July 23, 18S/I.

T0 @ZZ whom, t may concern,.-

Be it known that I, DAVID WHiriNe, a citizen of the United States, and aresident of Ashland, in the county of Ashland and State ot' Ohio, haveinvented certain new and use ful Improvements in Olover-Hullers, ot'which the following is a specification.

The invention relates to improvements in clover-hullers, and its natureand distinctive characteristics are fully described hereinafter.

In the accompanying drawings I illustrate a clover-huller embodying theinvention, Figure 1 being a central vertical longitudinal section ot'same; Fig. 2, a detached endview ofthe hulling-cylinder and its concave;Fig. 3, a vertical section of one of the hangers supporting the ends ofthe axle ot' the hulling-cylinder; Fig. 4, an end View of said hangerand axle; Fig. 5, a vertical transverse section on the line x x of Fig.l. Fig. 6 is a vertical transverse section ofthe machine directly infront ofthe concave and hulling-cylinder, showing the pivot-rod csupporting the lower section of the concave; and Fig. 7 is a detachedview of a portion of the side of the machine, illustrati ing the slots ccut therein to receive the ends of the pivot-rod c;

In the drawings, A denotes the feed-trough, wherein is suitably mountedthe thrashing or stemming cylinder B, o f usual construction. The innerend of the trough A rises above the conveyor-shaft C and terminates overthe adjacent end of the separating-frame D, which inclines upward towardthe rear end of the machine, and is mounted upon the crank-axles E.

Between the two sides of the machine the axles E have a series ofcranks, F, standing at different angles to each other, and upon each ofwhich is mounted an independent part,- G, of the separating-frame D.Each part G consists of a perforated bottom, H, and two notched sides,I, and is fastened upon blocks J, to which are attached the bars K,mounted upon the crank-axles E, and carrying pins orv wires L on theirlower surfaces.

Below the separating-frame D is an inclined board, M, leading to thehulling-cylinder N, which is mounted on an axle, O, and consists of theend pieces, supporting the cylindrical portion P, which is properlysupplied over its surface with brad-spikes Q. rlhe ends of the axle Orest in boxes R, which are sustained in (No model.) l

elongated lug V, which passes between the two portions V of the lowerend ofthe hanger S, being therein retained by a bolt, X, as indicated inFig. 3.

The hullingcylinder N is encompassed, as to its lower halt' and upperfront quarter, by the concave Y, consisting of the upper and lowersections, a b, respectively. The upper section, a., of the concave Y isrigidly aflixed in position, and the lower half is arranged to closearound the hulling-cylinder N, or to Abe opened therefrom, in the mannerindicated in Fig. 2, the pivot c permitting this movement. Ihe pivot oextends from one side of the machine to the other, and its ends passthrough eyes d on the bolts e, which enter lugs f, and are provided witha nut or nuts, g, for the purpose ot locking the bolt in any setposition in the lug.

The sides of the machine have elongated slots c, to receive the ends ofthe pivot c, so that when the bolt e is adjusted in the lug f the pivotc may be elevated or depressed, whereby the lower halt of the concave isbrought nearer or removed from the hulling-cylinder N.

The end of the concave Y farthest from the pivot c will be held inposition on each side of the machine, when the concave is closed, bymeans of the bolt m, which is hung in an eye, n, its lower end enteringa lug, p, to be insei-ted in the slot p when the concave is elevated,and being provided with a lockingnut, 1'.

The lower section of the concave Y, as will be observed, may be adjustedeither vertically or horizontally with relation to the cylinder N.

rIhe surface of the cylinder N and the inner surface of the concave Yare supplied with brad-spikes, upon the ends of which the seed ishulled.

Directly over the cylinder N is mounted the conveyer-shaft O, consistingof an axle carrying the detlecting blades or worm t, the purpose ofwhich is to operate as a feed to distribute the clover-heads over thecylinder N and to convey the tailings from the return-elevatoru. At theleft-hand end of the conveyorshaft O the blades t for a proper distanceare IOD deflected in an opposite direction to those 'on the main portionof the shaft,'and the object of this arrangement is to prevent the headsof clover Vfrom pressing or packing against the 5 side of the machine.

In rear of the hulling-cylinder N is the shaking-screen w, below whichare the inclines as, leading to the delivery-spout i, and forming achute for the blast from the fan z.

ro Below the rear end of the shaking-screen w is a worm-shaft, A, formoving the tailings into the lower end of the return-elevator u.

In the operation of the machine the clover is fed into the trough A,where it is acted upon in the usual manner by the thrashing or stemmingcylinder B, and moved upward upon the agitatingframe D, which separatesthe4 seed and heads from the stems, straw, &c., the latter passing outat the rear end of the machine, 2o while the former falls through saidframe upon the inclined board M, and passes thence to the cylinder N,their movement being facilitated by the pins L. The clover-heads arebroken and hulled by the cylqinderN and concave Y, and discharged uponthe shaking-screen w,

which sifts the seed upon the inclines x, andpermits the refuse to beblown out through the end of the machine. The cleaned seed is conveyedaway by the spout y, and the par- 3o tially-hulled clover-heads arereturned to the hulling-cylinder N by the elevator u.

The arrangement hereinbefore described of the hangers S, thehulling-cylinder N, and hinged concaveYis very advantageous,in that,

among other things, it avoids the usual labor of removing the cylinder Nwhen repairs are necessary or it is desired to remove the concave Y. Y

What I claim as my invention, and desire to secure by Letters Patent, is4o l. In a clover-huller, the combination of the hulling-cylinder N, themachine-frame, the concave Y, composed of sections a b, the pivotrod c,sustaining the slotted sections b, the eyebolts e, lug f,'nuts g g, andabolt, m, for 45 securing the said section when closed, substantially asset forth.

2. In a clover-huller, the combination, with the hulling-cylinder N,having a central axle, O, of hangers S, depending from beamsT ofthe 5omachine-frame, and having curved lower ends composed of parts W W, theboxes R, the flower end of' which having a lug, V, between parts W' W,and a screw, x, passing trans versely through the said parts WV and lugV, Asubstantially as set forth.

' 3. In a clover-huller, the trough A, sternnling-cylinder B, combinedwith the separating-frame D, worm-conveyer C, hulling-cyl- Minder N, andconcave Y, the worm-conveyer 6o being located directly over the cylinderN and fbetween the cylinder Band frame D, substantially as set forth.
